Role SummaryWe're seeking a Fluid System Development Engineer to support the design, development, and test of fluid systems that enable vehicle operation and reliability (fuel, cooling, hydraulics/pneumatics, lubrication, seawater handling, and related controls-depending on platform needs). You'll help take systems from concept through requirements, layout, prototyping, and qualification-aligned with how space and aerospace teams develop flight-critical fluid systems (pumps, valves, actuators, controls).
What You'll Do- Support architecture and detailed design of fluid systems: schematics (P&IDs), component selection, routing/layout, mounting, and serviceability.
- Size components and lines using first principles and simple models (pressure drop, flow rates, heat transfer) and validate assumptions with test.
- Partner with mechanical/electrical/software teams on sensors, controls, and fault detection for fluid subsystems.
- Create and execute development tests: leak checks, performance characterization, endurance screening, and instrumentation plans.
- Own tight feedback loops: capture issues, propose design changes, and re-test quickly with strong documentation.
- Support producibility: BOM rationalization, supplier engagement, assembly procedures, and verification checklists.
Who You Are- BS in Mechanical, Aerospace, or related engineering discipline.
- Comfortable working with physical hardware and learning hands-on (fittings, tubing, seals, pumps/valves, instrumentation).
- Strong fundamentals in fluids/thermo and an engineering mindset that balances performance, safety, and maintainability.
- Clear, collaborative communicator who can translate field observations into actionable design improvements.
Nice to Haves- Experience with P&IDs, pressure testing, hydraulic/pneumatic components, or thermal management systems.
- Familiarity with development programs that emphasize reliability, verification, and documentation discipline (common in aerospace/space).
What We Offer - Incredibly high-caliber teammates. You'll work directly with our co-founders Rylan, Scott, and Austin.
- A fast-paced, creative working environment that offers a lot of room for ownership and growth.
- Opportunity to join a meaningful mission that protects American and our Democracy.
- Salary Range: $77,000 - $100,000 annual base salary (final compensation will depend on experience and skill level.
- Startup equity options.
- Generous PTO, medical, dental, and free vision coverage.
Must be a U.S. Person due to required access to U.S. export controlled information or facilities. By applying, you confirm that you are a U.S. Person and can provide acceptable documentation verifying your status if selected.
